Abstract
A display device may include a plurality of tiled spatial light modulators (SLMs) imparting image information upon respective light beams to obtain image beams. Pupil steering optics are configured to steerably direct the image beams towards a same or different exit pupil locations within an eyebox of the display device, providing exit pupil replication and/or an expanded field of view. An eye tracking system provides location information of the user's eye, enabling the pupil steering optic to direct at least some of the image beams to a desired exit pupil location.
